Shockingly good article — correct identification of the root cause of performance issues being excessive dynamism and ranking of the solutions based on the value/effort ratio. Excellent taste. Will keep this in my back pocket as a quick Python optimization reference.

It's just somewhat unfortunate that I have to question every number and fact presented since the writing was clearly at least somewhat AI-assisted with the author seemingly not being upfront about that at all.

Being upfront about AI-assistance or no AI-assistance doesn't mean shit. Whether AI was involved is independent of what they state and there's no real way to fully prove otherwise.
